High-Temperature Rotary Valve

You can confidently entrust Jiangteng to provide customized design solutions for your high-temperature rotary valve requirements. Engineered for stable operation in high-temperature and high-dust environments, our valves feature superior sealing performance. Through the integration of heat-resistant materials, triple-sealing technology, and a structurally reinforced design, our equipment is guaranteed to deliver a long and dependable service life.

Why Choose Our High-Temperature Rotary Valve?

In the high-temperature conveying processes of industries such as building materials, chemicals, metallurgy, and electric power, a device's high-temperature resistance and sealing stability are directly linked to operational efficiency and safety. Jiangteng specializes in the field of high-temperature discharge; our product is designed to resolve numerous industry-specific challenges.

Problem 1: High-temperature deformation and short service life?

We utilize a one-piece cast housing made from 310S stainless steel or high-temperature alloys, featuring a reinforced rib design to resist deformation. Furthermore, through solution treatment, we enhance the material's heat and wear resistance, ensuring the device maintains structural stability under high-temperature conditions. This extends its service life by 3 to 5 times compared to standard discharge valves.

Problem 2: Air leakage, material leakage, or dust overflow?

As a professional manufacturer, our equipment features a unique triple-sealing system—comprising flexible graphite, spiral-wound metal gaskets, and high-temperature alloy sealing rings. Combined with an optional water-cooling jacket design, this system ensures an air-locking efficiency of up to 99%, effectively isolating high-temperature airflow, preventing material clumping and dust dispersion, and maintaining stable system pressure.

Problem 3: Frequent maintenance and high costs?

Our high-temperature rotary valve features a split-body structure and quick-release end caps, making the inspection and replacement of the rotor and sealing components simple and straightforward.

The external bearing housing is equipped with dustproof and waterproof protection, significantly extending bearing service life and reducing the frequency and cost of routine maintenance.

Problem 4: Unique operating conditions where standard models do not fit?

We offer comprehensive customization services: from material selection, sealing methods, and throughput capacity to connection dimensions, every aspect can be specifically designed to match your material characteristics, operating temperatures, and installation requirements, ensuring perfect compatibility between the device and your existing system.

Product Working Principle

The high-temperature rotary valve achieves continuous material conveyance and system air-locking through the combined action of a rotating impeller and precision seals:

1. Feeding: High-temperature material descends from the hopper into the pockets of the rotating impeller.

2. Conveyance and Sealing: The impeller rotates to transport the material, while a multi-layer sealing structure maintains constant, tight contact to prevent the upward or downward flow of hot air, thereby avoiding energy loss and material degradation.

3. Discharging: As the material rotates toward the discharge port, it falls by gravity into the downstream equipment, completing a smooth and steady discharge process.

Key Specifications

All models can undergo non-standard adjustments based on material characteristics—such as particle size, corrosiveness, and viscosity—to provide solutions that are truly tailored to specific operating conditions.

Our Process Advantages

1. High-Temperature-Resistant Structure: The high-temperature rotary valve features a one-piece cast body combined with a reinforced rib design, ensuring it remains free from deformation even under high-temperature conditions. The rotor undergoes solution treatment, providing exceptional resistance to wear and heat for long-term, stable performance.

2. Multi-Layered Sealing System: Utilizing a combination of flexible graphite and metal seals—with select models featuring water-cooled jackets—the system achieves a 99% air-locking efficiency, effectively preventing both air leakage and material spillage.

3. Low-Noise, Smooth Operation: Engineered with a precision reduction drive and a dynamically balanced rotor, the unit operates with noise levels ≤75dB, making it ideally suited for continuous-duty industrial environments.

4. Easy Maintenance Design: Features include quick-access end covers, externally mounted dust-proof bearings, and dedicated inspection ports, ensuring that maintenance is both simple and time-efficient.

FAQ

Q: What is the maximum temperature a high-temperature rotary valve can withstand? Is customization available?

A: Standard models can handle temperatures up to 800°C. We also offer customized solutions for extreme operating conditions—reaching up to 1000°C—utilizing specialized alloys and dedicated sealing systems.

Q: What should I do if the equipment experiences air leakage or material leakage?

A: In most cases, this is caused by worn-out seals or loose installation. We recommend the following steps:

① Replace the high-temperature seals;

② Inspect and tighten the end cover bolts;

③ If the housing is deformed, please contact us for repair or replacement.

Q: How do I select the appropriate model?

A: Please provide four key parameters:

① Operating temperature;

② Material characteristics (particle size, corrosiveness, etc.);

③ Required throughput capacity;

④ Installation space constraints.

Our technical support team will recommend the most suitable model or a customized solution tailored to your needs.

Q: What maintenance does the equipment require?

A: We recommend performing an inspection every 3 to 6 months (for high-temperature or high-dust environments, this interval should be shortened to 1 to 3 months).

Key areas to monitor include:

① Bearing temperature and lubrication;

② Condition of the sealing components;

③ Prompt removal of accumulated material;

④ Avoiding prolonged idling (running empty).

Q: Do you provide installation and after-sales support?

A: We offer professional on-site installation, commissioning, and operator training services, backed by a comprehensive after-sales support system. Should any quality issues arise during the warranty period, we provide free repairs or replacement parts.
